The rear brake uses the Shimano rear direct mount standard.Shimano Dura-Ace 9010R, Ultegra 6810R, 105 5710R, TRP T750, TRP T740, and Bontrager's rear brake off the new Madone will fit. There are more coming including adaptors so hydro brakes like Magura and SRAM can be used as well on the same mount.

Thanks for details, SuperD! My question may have come off a bit abrasive. I was just floored to see an Ultegra DI2 build at such a price point, and $2700 dollars more than the mechanical equivalent. I mainly wanted to clarify it wasn't a typo! I'm sure you have the numbers. And thanks for sharing the spec bump specifics. Knowing that the layup is different for both frame and seatpost does explain a little. It's just that for most people, UDi2 is the way in to electronic at a budget-friendly price point. For me, at least, I feel you guys may have missed the point by upspeccing that model so much. Let 9070 stand as the premium shimano electric, and use Udi2 to entice new electronic customers who are price sensitive.Anyway, the frame looks awesome and will no doubt do very well. Congrats, and I can't wait to read first rides!

1. Will the framesets (either the electronic version or the mechanical) be able to accommodate hydraulic shifting? Or is the owner obligated to buy a new frame when those systems soon come out?2. Have the geometry tables been posted anywhere?

Hydro shifters? If you are referring to the SRAM images leaked, those were a joke. If you are referring to the ACROS(?) system shown at Eurobike a couple seasons ago, then yes, their hydro shift housing would fit through our mechanically routed internal holes on the downtube of the AR1, AR3R, AR4, and AR5. You'd need the hydro cable guides off the Z2R or Z3R model. I have no idea how to detach and/or bleed that system though.

Geo will be published with the web launch to coincide with EB. If I were better at cut and pasting from excel into this BB I'd drop them in here but I trust you can wait a week.

Ummm... no, not the "leaked images" - those we determined to be fake long ago.ACROS is developing a Road shift system, as verified at Interbike 2012 and from insider contacts is very close to release.... and then, finally, word from your competition: viewtopic.php?f=3&t=113669&start=90#p996220As you know, WW aren't fools to fall for the fake images that float around the internet!

That said, the reason I asked is because some of us choose to keep a frame or components for several years and upgrading selectively rather than buying new things all the time. Well, some of us. I like this frame, and potentially if the geometry works, it is worth consideration - but I want to know if it will accommodate the near future. The new AR series has two separate and distinct frames: one designed for eletronic, the other for mechanical. On the other side, the newest Cervelo RCA has one frame that can take on all three drivetrain & shift options, with a simple switch of some small grommets.
